Abstract: The mobile terminal-oriented complex condition geographic information query method, device and medium are disclosed, and the method includes: determining geographic information query condition semantics, and setting complex condition query contents according to condition semantic regulations; based on a preset query rule, analyzing conditions meeting the rule, and obtaining attribute information of target objects and attribute information of condition objects forming complex conditions; and according to the attribute information of the target objects and the attribute information of the condition objects, performing server calculation query and returning a geographic information query result. Based on collection, storage and classification of the geographic entity position information, the geographic entity position information of a specific type and space limitation is inquired, so that the function of simultaneously limiting the conditions of target objects by the mobile terminal is enriched.
